Additional material examined. BRAZIL: Amazonas: Manaus: Igarapé Tarumã-Mirim [3.0°S 60.2°W]: 1 ♂, 1.XII.1987, unknown collector ( INPAAbout INPA)GoogleMaps  ; 1 ♂, 19.II.1988, unknown collector (INPA 4478); 1 ♂, 20.I.1988, unknown collector (INPA); 1 ♂, 6.XI.1987, unknown collector (INPA); 1 ♂, 7.III.1988, unknown collector (INPA 4 476); 1 ♂, 8.III.1988, unknown collector (INPA 4477).

Etymology. The epithet, to be treated as a noun in apposition, is a word used in Brazil for black water flooded forest in the Amazon, since the specimens reported here were collected from that habitat.

Diagnosis. Males of this species can be recognized by having the embolus with no abrupt angle ( Fig. 44View FIGURES 44 – 49) (in E. simoni  , the embolus extends straight distally and then forms an angle at its middle; see Fig. 11View FIGURES 10 – 16). Also, males of E. igapo  sp. nov. have larger terminal apophysis and smaller RTA ( Fig. 44View FIGURES 44 – 49). Females of E. igapo  sp. nov. have round copulatory openings, the spermathecae are larger and the dorsal coupling pocket is not centralized, almost paired ( Figs 43View FIGURES 39 – 43, 48–49View FIGURES 44 – 49).

Female (paratype): Total length: 6.22. Although the specimen is not perfectly preserved, color pattern as described for the genus ( Fig. 42View FIGURES 39 – 43). Carapace 3.07 long, 2.07 wide, 1.46 high. Ocular quadrangle 1.54 long. Anterior eye row 2.00 wide and posterior 1.84 wide. Leg formula: 3412. Length of femur: I 1.51, II 1.51, III 2.02, IV 1.78; patella + tibia: I 2.06, II 1.87, III 2.09, IV 1.94; metatarsus + tarsus: I 1.39, II 1.34, III 1.90, IV 2.02. Leg macrosetae: femur I d1-1-1, p1di, r0; II=III d1-1-1, p2di, r0; IV d1-1-1, p0, r1di; patella I=II 0; III=IV p1, r1; tibia I p0-1-1, r0, v2-1 r-2; II p1-1-1, r0, v2-1 r-2; III=IV p1-1-1, r1-1-1, v1 p-0-2; metatarsus I=II v2-2; III p1-0-2, r1-1-2, v1 p-1r-2; IV p1-1-2, r2-1-2, v1 p-1r-2. Epigyne as described for the genus ( Figs 43View FIGURES 39 – 43, 48–49View FIGURES 44 – 49).

Biology. According to Adis (2002: 8), the type locality is covered with a clayish-sandy soil, being inundated for about four months every year, which agrees with the description of the locality in Belém where E. simoni  is found. This seasonal igapó in Manaus  has been periodically flooded for at least one million years.

Distribution. Known only from type locality.
